Iron ore extraction techniques ScienceDirect

Jan 01, 2015· Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this

Extraction of Iron from its ores, Iron dressing, Reduction

Oct 23, 2018· Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

Processes and Procedures in the Extraction of Iron

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
